What are the characteristics of malnutrition in the root system of planted crops?

As the saying goes, "water is the leg of fertilizer, and the root is the mouth of fertilizer", and the key to the growth and development of crops is the health of the root system. In the same way, many physiological diseases are closely related to damage to crop roots. So, which physiological diseases are caused by a bad root system?

1. Yellowing

Although yellowing is manifested in leaves, most of the problems are caused by a variety of root system impacts, including sudden environmental changes and soil quality degradation. These causes lead to an impairment of the normal physiological activity of the root and a decrease in its absorption capacity.

2. Progeria

Most crops with premature senescence are caused by the degradation of the root system in the middle of its growth. The root system weakens, which leads to a gradual weakening of the tree. This is especially true during the season when temperatures are low.

3. Slow growth

Continuous cropping obstacles, unreasonable fertilization, soil compaction salinization, and unbalanced growth of soil beneficial bacteria will affect the normal growth of crops. Specifically, the root system is hindered from absorbing nutrients, and the plant growth is slow or even not long.

What causes root problems?

1. Watering too often and too heavily, the phenomenon of rooting occurs, which leads to the stunting of root growth.

2. Unreasonable fertilization leads to fertilizer fermentation, heating or release of harmful substances, resulting in root poisoning, and in severe cases, crop death.

3. Unhealthy soil will also affect the growth of roots. Stickiness, compaction, and salinization can all endanger the health of the root system.

How to raise roots and protect roots?

1. Reasonable watering:Dry and long roots, wet and long seedlings. If you want the root system to grow well, you need to be moderately dry, and the frequency and amount of watering should be controlled.

2. Increase the application of microbial fertilizer:You can add 2-3 bags of Ongro per mu when fertilizingOnnongleIt is a microbial fertilizer made by fermentation after mixing Chinese herbal medicine, seaweed and minerals, adding 8 kinds of beneficial microorganisms such as nitrogen-fixing bacteria, carbon-fixing bacteria, and Bacillus thuringiensis, which is rich in high-energy substances and a variety of mineral elements. It can improve the soil, promote the growth of the root system, inhibit the growth of harmful bacteria and improve the activity of enzymes.

3. Potassium supplementation:The distribution of potassium in metabolically active roots is high, and it has the functions of smooth progress of various metabolic processes, promoting plant growth, enhancing resistance to diseases and pests and lodging. Therefore, each acre of land should be flushed, drip irrigated or sprinkled in a timely mannerMineral source potassium fulvic acid1-2 bags, which can also promote root development and enhance crop stress resistance.

Rooting and Rooting**:R. solanacearum and Trichoderma harzianum shrub roots. Chinese herbal medicine biopesticides and microbial agents Trichoderma harzianum can remove pathogenic fungi and bacteria in the soil, protect the root system, promote rooting, and reduce the occurrence of soil-borne diseases such as root rot.

Promote wound healing, regulate the balanced growth of crops, and significantly improve the ability of crops to resist diseases, drought, cold, waterlogging and viruses.

The first is to observe its leaves, because the roots are malnourished, the leaves must be yellow, the second is to pinch with your hands, if the leaves are soft at the roots, it proves that there is a lack of nutrients, and the third is to observe its growth, malnutrition, the plant must grow very slowly, and the flowers are not good.

Poor roots do not manifest themselves in the upper part of the plant in a short period of time, but after a long time, the stem will be weak and long, the leaves will turn yellow and wilt, and the plant will die unconsciously.

It grows very slowly, unlike other normal plants; There is also the fact that the root system is prone to premature aging; There are also some cases where the leaves turn yellow, which means that the nutrition cannot keep up.

The root system of the plant is underdeveloped, probably because of watering, fertilization, potting soil, light. Therefore, it is necessary to find out the cause and then prescribe the right medicine, which is not necessarily caused by fertilizer. Of course, you can also choose to use some phosphate fertilizer to promote plant growth. Let his roots develop.

It is very likely that the root system of the plant is pilling, so it is like this, not only because of fertilizer, but also because of potassium and phosphorus fertilizers.

The key to plant growth lies in the root system, the roots are deep and leafy, and only when the root system is developed, the plant can be strong. There are many reasons why the root system is not vigorous, and when you encounter poor growth of garden plants, you can find the solution by looking for the cause, prescribing the right medicine. The root system of plants is not developed, generally related to potting soil, fertilization, watering, and light, and the weak root system will lead to poor growth of seedlings, and less fruit in the later stage, and the fruit quality and yield will also decline, so we must find out the cause and prescribe the right medicine to avoid affecting the harvest in the later stage.

Normally, the root system of the plant is underdeveloped, with the element phosphorus.

There is a direct relationship. Phosphate fertilizer is to promote roots and flowers, if there is a lack of phosphorus in agricultural planting, the plant will be short (the reason is that the root system is underdeveloped, can not support strong and tall plants). At the same time, because the root system is not developed, the plant can draw less nutrients from the soil, which in turn affects the vigor of the plant.

Excessive fertilization or use of unrotted farmyard manure: Excessive fertilization can lead to root burning, unrotted farmyard manure releasing heat, or soil-borne diseases that can damage plant roots. <>

Therefore, it must be fully decomposed before it can be used, sheep dung, cow dung, pig dung, human and livestock and other farm fertilizers should not be used easily, and it can only be used after it is fully decomposed. In addition, ferrous sulfate is used to improve the soil.

Or too much lime, resulting in soil poisoning, affecting the development of the root system, if the fertilizer fermentation phenomenon, that is, the fertilizer in a certain temperature and other conditions, decomposition and release some harmful substances, then it will cause plant root poisoning, directly cause crop death, this dead seedling phenomenon will generally last for 30-40 days, and then it will be terminated. <>

To solve the problem, first of all, the fertilizer must be applied early, about 40 days before planting, and it must be irrigated after deep application. Some growers plant more crops in the spring, and the planting time is more concentrated, which will cause the planting method of some crops to be incorrect, so that the root system of the crop can not be relieved immediately after planting, and it is very easy to cause the phenomenon of dead trees and rotten seedlings. After flooding, the roots will be soaked in water in the previous stage and unable to absorb nutrients, resulting in lack of oxygen and causing the plant to wilt.

Of course, drought can also cause root nutrient deficiencies**, resulting in limited crop growth. <

Fertilization is necessary in the process of plant breeding, and many flower friends do not intentionally buy fertilizer for all parts of the plant. It can lead to unbalanced plant growth. The root system is underdeveloped, which may be due to a lack of nitrogen fertilizer.

This may be because the subject has never tried fertilization in the first place, or has never tried nitrogen fertilizer, and therefore has insufficient root development. In the later stages, if you want the root system to develop, you need to give the plant enough nitrogen fertilizer so that the root system can develop naturally.

Lack of phosphorus and potassium fertilizers can also lead to poor root development. During the cultivation of plants, these two fertilizers should not be missing, and it is best to replenish them every once in a while. If you use nitrogen fertilizer this time, you can replace it with phosphate and potassium fertilizer next time.

It is not recommended to use the amount at a time, which is easy to cause fertilizer loss. The root system is a key part of plant growth and development. If the root system grows well, the plant will naturally appear more luxuriant.

In the process of plant breeding, fertilization must not be forgotten. It is not recommended to use nitrogen fertilizer too often, although the root system will be underdeveloped due to the lack of nitrogen fertilizer, but excessive application of nitrogen fertilizer can also lead to branch and leaf growth.

Soil is a fundamental part of green plant conservation. Rational allocation and utilization of soil is the key to green plant conservation. It is best to use a third of the configuration soil, humus soil, pasture soil and coarse sand to maintain the greenery.

This soil is "good and not bad" to ensure that it is loose, breathable, free of standing water and slightly acidic in pH, and is the basic soil suitable for most plants.

If you water half of the water, the upper part is wet and the soil in the lower part is still dry, which will also cause a reaction for plants that need water in particular. Half of the water has a great impact on the growth of plants. Especially when temperatures are high, the air is particularly dry in spring, summer, and autumn.

Plants, flowers, and plants need water and must be watered adequately. As long as the pot has drainage holes, the potting soil is breathable and drainable, and there is no problem with watering thoroughly.

It is because of the lack of farm fertilizer, because farm fertilizer is very important for planting plants, if the plant is sprayed with farm fertilizer, it can definitely improve the production of plants, can also make plants grow better, can also prevent plants from pests and diseases, and can also prevent plants from wilting.

It may be because of the lack of potassium fertilizer, timely supplementation** can help the plant's root system to get better development, and can also make the plant's root system develop better, which can help the plant grow better.

Lack of nitrogen fertilizer can be a lack of phosphorus, potassium, or root rot due to overwatering.

Fertilizing plants requires fertilizer, but fertilizing is really hard. Many flower friends do not buy fertilizers for various parts of plants. Choose the fertilizer at home, that is because the plant growth is uneven, usually the plant root system is not developed, and the phosphorus is directly related.

Phosphate fertilizer is to promote root and flowering, and the lack of phosphorus in agricultural planting will make the plant smaller. (Because the root system is underdeveloped, it can't support the strong and tall **). In addition, due to the underdeveloped root system of plants, the soil absorbs very few nutrients, which in turn will affect the vigor of plants.

There is a saying that "the roots are deep and the leaves are thick", and only when the root system becomes stronger and deeply rooted underneath, the leaves will flourish and the momentum will become stronger. Nitrogen fertilizer can play a role in making plant roots stronger and foliage more lush. However, for plants with too weak root systems, it is necessary to apply thin fertilizers in order not to burn the roots so that the root system is too weak.

That would be irreparable. Some grow well, some don't. Its root system is underdeveloped, which may be due to insufficient nitrogen fertilizer.

It may be because the cultivated plants have not tried fertilizer, or it may be because they have not tried nitrogen fertilizer, so the root system is not developed.

In order for the root system to develop in the later stage, it is necessary to supplement the plant with enough nitrogen fertilizer, so that the root system will develop naturally. In addition to nitrogen fertilizers, there is a shortage of phosphate fertilizers and underdeveloped root systems, so these two fertilizers are indispensable in the process of cultivating plants. It's best to replenish at regular intervals, but don't use both.

If you use nitrogen fertilizer this time, you can switch to phosphorus and potassium fertilizer next time. It is not recommended to use a large amount at a time, as it is easy to cause fertilizer damage. Phosphate fertilizer can make flowers bloom more vividly, strengthen the root system of flower plants, and make plants with weak root systems energetic and lively.

Therefore, flowers can be fertilized with phosphorus and potassium fertilizer, or with potassium dihydrogen phosphate aqueous solution fertilizer. For the same reason, thin fertilizers are needed. Do not apply fertilization frequently until the root system has recovered.

Please do not apply too much fertilizer at once. Then the root system of the flower will simply die. In other words, it is often said that getting to the bottom of the matter.

It is likely that there is a lack of chemical fertilizer, and you should usually fertilize it regularly, so that the plant can grow well, and if the root system is very thin, you should also pay attention to watering more, so that the plant can grow strong.

This situation is caused by nitrogen deficiency fertilizer, and some organic fertilizer can be buried or urea can be directly sprinkled to top dress.

This situation is caused by potassium deficiency, which can be alleviated by chasing compound fertilizer every other month.

Deep soil ploughing. If the root is deep to be leafy, if the long-term rotary tillage, the tillage layer is less than 20 cm, the lower part forms a hard plough low layer, impermeable and impermeable, affecting the root system of crops, resulting in the crop root system is too shallow, not resistant to drought and waterlogging, through deep ploughing, breaking the bottom layer of the plow, the root system is not good, there are many reasons to bring, such as: soil compaction acidification, fertilization and sprinkling, etc., resulting in the root growth is hindered, the amount of water is insufficient, the fertilizer effect can not be diluted and dissolved into the soil for root absorption, and lack of fertility.

Apply more organic fertilizers. The bottom fertilizer is increased with organic fertilizer or water-soluble fertilizer containing humic acid, and the soil organic matter content is high, which can provide sufficient nutrients on the one hand, and loosen the soil on the other hand, which is conducive to root growth and rooting; While paying attention to the supply of organic and inorganic nutrients to crops, we also pay attention to the physical conditions required for root growth, including suitable porosity, pH, water retention and permeability, etc., so a good organic ecological soilless cultivation substrate is not only a high-quality organic fertilizer, but also a good soil amendment.

The root system of vegetables is like the stomach of a person, only with a good root system can absorb nutrients in the soil, can grow strong seedlings and strong trees can produce high yields. In the process of watering, we must use microbial agent rooting fertilizer to promote the development of the root system, such as the use of rooting source, first of all, before planting, it is necessary to maintain the soil permeability and a good microbial environment, at this time it is best to make a general assessment of the soil, if the soil is compacted, saline-alkali heavy, it is best to add biological organic fertilizer, organic fertilizer can increase the air permeability of the soil.

If the plant root system is not good, the first thing to see if there is a problem in the soil, soil continuous cropping, excessive use of chemical fertilizers and neglect of the use of organic fertilizers, low soil pH, poor air permeability will cause poor root system, and we should start from soil improvement! Improve the soil, mix and mix with water and fertilizer to ferment into slurry or liquid-like organic fertilizer, sprinkle the soil with appropriate amount of water, and turn it deep with uniformity, so that the fertilizer effect conversion is mixed into the soil for root absorption.
